LIFTIN G DEVICE.

Specification of Letters Patent.

Application filed April 16, 1921. Serial No. 461,927.

To all whom it may concern} 7 Be it known that L'Jorix JOLLY, a citizenof the United States, and a resident of Hutchinson, in the county ofReno and State of Kansas, have invented certain new and usefulImprovements in Lifting Devices, of which the following is aspecification.

This invention relates to alifting device, particularly adapted forremoving plates or sections from an electrical storage battery.

The object of the invention is to provide a device of the abovecharacter by which a section of a storage battery including the usualpositive plate assembly and negative plate assembly may be lifted fromthe battery jar in an expeditious manner without injury to the plates.

Other objects and objects relating to de tails of construction,combination and arrangement of parts will hereinafter appear in thedetailed description to follow.

The invention is illustrated by way of example in the accompanyingdrawings, in which:

'Figure 1 is a side elevation of the lifting device as when inoperation,

Figure 2 is aperspective view of theliftin device, v

*igure 3 is a front elevation of the lifting device as when inoperation,

Figure at is a top plan view of the support for the lifting device, saidsupport being positioned upon a storage battery,

Figure 5 is a cross section taken substantially on the lines 55 ofFigure 3.

Referring to the drawings more particularly, A indicates generally abattery casing or box, said battery being of the usual six volt type,and consisting of the usual three.

sections, 10, 11 and 12, each section having each pair being connectedwith a positive plate assembly while the other is connected plateassembly in a manner well known.

The plates are of course held within a hard rubber jar in the usualmanner, and the sections 10, 11 and 12 are covered with the usualinsulating compound. In carrying out my invention I provide a pair ofbase members 17 and 18 each of which has extended from a central pointthereof a vertical member 19. The member 17 is also formed with a pairof end members 20 extended at right angles therefrom and from the upperedge thereof, as shown. Each member is provided with a centrallongitudinal slot 21, and the base member 18 is provided with a pair ofstuds 22 one at each end thereof, which are adapted to be slidinglypositioned in the slots 21 of the cross members 20. Each stud isthreaded and provided with a wing nut 23, by which the members 21 may beclamped to the base member '18.

Between the upper ends of the members 19 there is suitably journaled ashaft 24, said shaft having a crank arm 25 and a handle 26 formedtherewith, by which the same may be manually rotated. The shaft is heldagainst longitudinal movement by means of a pair of collars, asindicated at 27, and the portion between the members 19 carries awinding drum 28. The collars 27 are adjustably held by set screws, asshown, and thus permitting the members 19 to be moved outwardly orinwardly corresponding to the movement permissible by the members 20.The drum 28 has attached at its longitudinal center the one end of achain 29, said chain being attached by the means of an eye bolt 30,- andsaid eye bolt being threaded through the drum and into the shaft 24, asshown in Figure 5, thereby holding the drum against movement withrespect to the said shaft.

With the lower end link of the chain 29, there is connected a clevis 30,the pin 31 of which extends through an opening at the longitudinalcenter of the beam 32. On each end of the beam 32 there is pivotallyconnected a clevis 33, said clevises each having suspended therefrom apair of tongs as generally indicated at 34, each of said pair of tongsbeing connected byv its respective clevis through the means of a pair ofchains 35 and a ring 36, as shown. e jaws 37 of each pair of tongs areformed with a V-shaped recess as at 38, the purpose of which will laterappear.

In the operation of the present device,the two base members 17 and 18are positioned upon the battery as shown in Figure 4. The base membersextend transversely of the battery and the distance between said membersis adjusted by the means of the Wing nuts 23, so that they straddle asection of the battery. Different types of storage batteries havesections which vary in width and consequently the means for adjustingthe distance between the base members 17 and 18 is of an advantage. Thecompound is of course removed about the section to be lifted so that itis free to slide from the rubber jar within which it is' en closed. Thebeam 32 is then lowered and the tongs 34 attached to the connectingposts 13, the V-shaped recesses 38 formed in the jaws 37 permitting thejaws to secure a tight grip upon the connecting posts 13 when the beam32 is lifted, and the jaws 37 are closed. By rotating the crank 25, thebattery section with which the tongs are connected may be lifted fromthe battery jar in an easy, manner. The fact that the pull on the tongs84' is balanced by the beam 32 permits the positive and negative plateassemblies of the battery section to be evenly lifted from the batteryjar and thus eliminating the danger of injuring said assemblies; 7 Y

While I have shown and described the preferred form of my invention, Iwish it to'be understood that I am aware of the fact that thebonstruction, combination and arrangement of parts may be changed bythose skilled in the art without departing from the spirit of myinvention, as indicated by .the appended claims.

-l.- A lifting device of the character de scribed, comprising" a pair ofbase members, a pair of cross bars formed on one of said members, meansby'which said cross bars may be adjustably connected with the other basemember for varying the distance between said base members, a verticalsupport extending from each base member, a

shaft carrying a winding drum journaled between the upper ends of saidsupports,

said shaft being adapted to permit outward movement of the supports withrespectto the drum, adjustable means by which the having its one endattached to said drum,

means by which a load may be attached to said chain, and means byfwhichthe distance between the supports may be adjusted.

3. In a lifting device of the character described, comprising a pair-ofbase members, a pair of cross'bars formed on one of said base members,each having a longitudinally extending slot, a pair of studs formed uponthe other base member, one near each end thereof and adapted to slidewithin the slots of said cross bars, a wing nut by which said cross barsmay be adjustably held, a vertical support extending from each basemember, ashaft carrying a winding'drum journaled between the upper endsof said supports, said shaft'being adapted to permit outward movement ofthe supports, a chain connected with said winding drum,

means by which a load may be connected to said chain and crank means bywhich said drum may be manually rotated;
